A couple points come to mind which may affect your assumptions:

Mechanization and technological advancement have been boogeymen since the dawn if the industrial age, and while it has made jobs obsolete, it has never caused systemic unemployment.

Economically, labor is the most scarce of all commodities, and skilled labor even more so. As technology multuplies the productive capacity of workers, labor is freed up for new industries.

The turmoil of progress has been used to exploit fear and seize political power though. Political plunder is always a probable result from such upheaval.

Lastly, I remain skeptical of the promised abilities of AI. GIGO remains the adage of computers as they advance. If memory serves, my desktop computers approach the processing power Data's positronic android brain as stated in Star Trek: The Next Generation. It's not jsut a matter of processing power and command tree subroutines.

My background in mechanical and architectural design along with my forays into economics and philosophy lead me to be skeptical of any claims of the promised singularity occurring any time soon. If it does, awesome. But I won't hold my breath waiting for that or the Zeitgeist Project promises.
